Java中的“Chunk :: new”中的“::”（双冒号）运算符是什么意思？

Question

I am getting hs_err_pid fatal logs from a tomcat process, and inside the log it says

#
# A fatal error has been detected by the Java Runtime Environment:
#
# java.lang.OutOfMemoryError: requested 1035152 bytes for Chunk::new. Out of swap space?
#
#  Internal Error (allocation.cpp:215), pid=2060, tid=3980
#  Error: Chunk::new
#
# JRE version: 6.0_21-b07
# Java VM: Java HotSpot(TM) Server VM (17.0-b17 mixed mode windows-x86 )
# If you would like to submit a bug report, please visit:
#   http://java.sun.com/webapps/bugreport/crash.jsp
#

My question isn't specifically about the OutOfMemoryError, but about how to interpret the Chunk::new phrase.

I see here that apparently the double colon is an operator in Java, but I don't know for sure what it does. Would that have something to do with my situation?

Answer 1

It doesn't mean anything in Java before version 8 (see this question ).

What you're seeing refers to C++ code. The first word is the class name, second is the method name. The :: itself is called the Scope resolution operator .

The error you're getting is from the C++ code of the JVM itself.

Answer 2

This indicates Java has failed to acquire more memory from the operating system.

JVM you are using is developed on C++. but JVM things are vendor specific.

There is nothing to do with :: this operator.
